摘要： A relay control circuit for use with a relay having a coil voltage input. The relay control circuit includes a first input to receive a first voltage capable of energizing the relay, a second input to receive a second voltage, less than the first voltage, that is capable of maintaining the relay in an energized state, and means, responsive to a relay control signal having one of a first state and a second state, for switchably coupling the coil voltage input to the first input in response to the relay control signal having the first state, and for switchably coupling the coil voltage input to the second input in response to the relay control signal having the second state.

摘要： Power supplies and methods of use thereof are provided, where a power supply includes an input configured to receive input AC power an output configured to provide output AC power to a load, at least one power converter coupled to the input and configured to convert the input AC power into the output AC power, a controller coupled the at least one power converter. The controller is configured to adjust at least one parameter of the output AC power provided by the at least one power converter, detect, in response to adjusting the at least one parameter of the output AC power, at least one of an adjusted input AC power or an adjusted output AC power, and determine that a fault has occurred based on the at least one of the adjusted input AC power or the adjusted output AC power.
